You are operating a loaded tractor-semitrailer at expressway speeds when a sudden steer-tire blowout occurs, causing a violent pull toward the left. To maintain directional control and prevent a catastrophic collision, which driving procedure must you immediately execute?
- AImmediately slam on the service brakes while counter-steering aggressively to bring the vehicle to an abrupt stop within the lane.
- BEngage the engine retarder and apply continuous snub braking to force rapid deceleration before the tire rim sustains heat damage.
- Grip the steering wheel firmly with both hands, stay completely off the brake pedal, allow the vehicle to coast down, and steer gently onto the shoulder.Answer
- DApply the trailer hand valve to stretch the combination and steer sharply in the direction of the vehicle pull to initiate a controlled slide.
Answer
Grip the steering wheel firmly with both hands, stay completely off the brake pedal, allow the vehicle to coast down, and steer gently onto the shoulder.
Holding the steering wheel firmly with both hands counters the violent physical pull created by the blown tire. Staying off the brake pedal is vital because braking transfers vehicle weight forward onto the collapsed tire, causing the rim to dig in or the steering to pull uncontrollably. Allowing the vehicle to coast down naturally keeps the combination stable until speed is low enough to safely maneuver off the roadway and apply light braking.
